I've been torturing myself doing this for bit over a month now, 3-4 times each week, now doing 6-7 sets of 5 reps, probably shit form but its getting better and my plank time is improving about 5 secs each week. (i only use plank for testing now)

This is true

>Still too easy? Do it from a standing position
I already do 3x12 standing roll-outs after my workout (3x9 on deadlift days).
Any way to up the intensity further?

Do more reps?
Try and do longer negatives and stop when in plank position for about five seconds. Really focus time under tension

I'm expecting this to appear in sir's new years comic.

Thanks, I'll try that.

hurts my lower back after 3 reps. I'm guessing my core is just too weak do one.

how can I make them easier so I can work up to all this.

Pain is usually caused by going to far forward and your back sagging during the roll out. Don't go as far forward, so you're not completely extended.
When you're comfortably doing reps you can extend further bit by bit.
